That's very interesting. Please keep me in the loop when you make progress into that direction. Maybe something into the direction of augmented reality?
I tried AR with a homemade 'cardboard viewer' and after that a Homido with an Android phone and my pandora as keyboard but because the phone had only 1 camera and the glasses are way too heavy to walk with it was an absolute pain... Technology will improve there but it's definitely not there yet.
